    To human eyes, the world at night is a formless canvas of grey. Many nocturnal animals, on the other hand, experience a rich and varied world, bursting with details, shapes, and colors. What is it, then, that separates moths from men? Anna Stöckl uncovers the science behind night vision.
    Lesson by Anna Stöckl, animation by TED-Ed.

    2:12 -- Nikola Tesla believed we can do that too, he once thought we could see brain activity or project our thoughts using this technique, and maybe it could be the reason for how we sometimes "see" our imagination. it perhaps is more perceptive in cats because they have more visual neurons related with vision and projection! awesome!

    @darkenergylambda 8 лет назад +22

    So in ways an astronomer/photographer understands:
    Tarsiers have bigger lenses = more photons
    Toads have a slower shutter speed/longer exposure = collect more photons at the expense of image refresh rate
    Moths have larger pixels = more photons per pixel

    • @GumaroRVillamil
      @GumaroRVillamil 8 лет назад +16

      owl eyes work like the tarsier's, they're front-facing and are very large for their body size. while they do see quite well, their main advantage is hearing. They have asymmetric ears that allow them to better pin point sounds. Also their round, slightly concave faces and face feathers help them to better focus sounds toward their ears, thus allowing them to hear the faintest sounds of their prey.

    i already knew this, because my dad is a photographer explained ISO to me :)
    big eye monkey explaination:
    this is also why a DSLR takes better low light pictures than your smartphone, because more light falls on each pixel because the sensor surface area is larger :)
    frog explaination:
    the amount of light per pixel depends on the sensor (and therefor pixel) size and the photons that hit the sensor/pixel
    that's why if you have a camera with manual controls, you can take photos in the dark that look good, but if the subject or the camera moves the image will be blurry.
